TURBINE FOR ROTARY TUBE CLEANERS.

Application filed August 21, 1924.

i type.

The primary object of the present invention is to provide a turbine forrotary tube cleaners of compact but comparatively simple construction.The simplicity of its construction permits it to be quickly assembledor, in case of the necessity for making repairs, it can be quickly andeasily taken apart to substitute new parts. Breakage of any parts,however, is not apt to occur as the device contemplated by the presentinvention is one that is composed of rather substantial and sturdyparts.

With this and other objects in view the invention consists in certainnovel details of construction and combinations and arrangements of partsall as will hereinafter be more fully described and the novel featuresthereof particularly pointed out in the appended claims.

In the drawings,

Figure 1 is a longitudinal sectional view of the turbine,

Fig. 2 is a sectional view on the line 2-2 of Fig. 1,

Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 1.

The turbine of the present invention comprises an elongated cylindricalbody portion preferably composed of two sections, a main section and asupplementary end section 11, the section 11 being removably secured byscrew threads to one end of the main section. At the end to whichsection 11 is attached section 10 is provided with a cen tral bore 13 inwhich is secured a bushing 14 and in the inner terminal of said bore atthe opposite end of said section 10 the latter is made hollow as at 12for the accommodation or reception of parts to be presently described.At the end to which section 11 is attached the central bore 13 isenlarged somewhat to provide a socket into which a plug 15 may bescrewed to close the central bore for a purpose which will presentlyappear. Arranged circularly around the central bore 13 is a series ofair passages 16 extending axially of the body 10 and these passagesemerge into the hollow portion 12 of the body. Removably inserted in thehollowed portion 12 of section 10 is an annular member 17 which has asleeve-like portion abutting against the reduced portion of the SerialNo. 733,414.

housing to space the annular portion of said member somewhat away fromthe bore 13. Said member and its sleeve-like portion have acentral bore3 which forms a continuation of the central bore 13 in the body andjournaled in the bore 13 of the body and the bore 13 of member 17 is therotatable shaft 18 which carries a rotor 19.

The rotor 19 is positioned at the end of the body with the annularmember 17 interposed between it and the hollow portion 12 of the housingwhich hollow portion, after the member 17 has been inserted, formssubstantially an air chamber. However, to permit the air flowing throughthe passages 16 to the chamber 12 to be delivered to the rotor 19 saidmember 1'? preferably has formed in its periphery a plurality of airpassages 20 which are termed at an angle to properly deliver the air tothe pockets 21 formed by the blades of the rotor. A continuation -18 ofthe shaft 18 is secured to the rotor 19 and carries at its outer end thecleaning tool 22, a universal joint of ordinary construction preferablybeing interposed between the rotor and the cleaning tool to allow thetoo-l to properly engage the walls of the tube,

being cleaned.

The end section 11 of the body is hollowed out as at 241- and isprovided with interior screw threads for the connection for supplyingthe air under pressure or other motive fluid to the body. As will beapparent, the air supplied to the interior of section 11 will passthrough the passages 16 to chamber 12, thence through ports 20 in member17, and into the pockets 21 formed by the turbine blades, the action ofthe air on the rotor resulting in the cleaning tool being rotated.

The shaft 18 is secured in the housing by an ordinary nut and washer 25attached to its end and any thrust strains created by the tendency ofthe shaft to move longitudinally of the housing will be taken up by thean nular shoulder 26 formed integral with the body 10 at the inner endof the socket in which the plug 15 is located. The socket, therefore,not only provides a shoulder which functions as a thrust bearing but italso serves the purpose of receiving the plug 15 which prevents themotive fluid entering the central bore, the entire supply of motivefluid thereby necessarily being compelled to flow through the ports orpassagealtli To disassemble the turbine it is'only necessary toremovethe end section 11 and then the plug 15, after which the shaft 18 isturned While the nut 25 is held stationary.

This will result. in the backing off of the.

a closure torthe reduced end of said central bore, a removable member inthe enlarged portion of the bore having a series of air passages thereinand a central bore arranged in alinenient with the reduced portion-o't'the central bore of the body, a shaft journaled in the central bores ofthe body and removable member whereby said shattvhas' an extendedbearing, and a turbine wheel mounted on the shaft with said removablemember interposed between it and the reduced portion of the bore in thebody, the air passages in said removable member being disposed at anangle to the axis of rotation of said shaft and turbine.

2. The combination ot' a body having a central bore of reduced diameterat one end and a plurality of air passages in said body at said end,said passages discharging into the enlarged portion of said centralbore, a closure for the reduced end of said central bore, a removablemember in the enlarged portion of the bore having a series of airpassages therein and a central bore arranged in alinement with thereduced portionlot the central bore of the body, a shaft journaled inthe central bores of thebody and removable member, a turbine wheelmounted on the shaft With said removable member interposed between it.and the reduced portion of the bore in the body, the air passagesin saidremovable member being disposed at an. angle to the axis of rotation ofsaid shaft and turbine, aremovable headon said shaft, and an annular,integral flange in the reducedcentral bore of the body against whichsaid head contacts to take up thrust strains.
